    Please try to run the System File Checker tool (SFC.exe) by taking following these steps:

    1. Open an administrative Command Prompt window.

    2. Type following command and then press Enter.

               sfc /scannow

    3.  After the scan is finished, try to install updates again.

     

    If it can’t work, please try to reset the Windows Update Components, please refer the following link.
